Maintenance free ball joints

Anyone have an update on these after running them for awhile?
I put a set on a car over a year ago. The car maybe has a thousand miles since and there appears to be slight movement, very slight. Do you retorque these? I am having my doubts about them, if I can feel movement after 1000 miles. These are the Delta brand.
